Stalk Nitrate Sample Submission Midwest Labs Portal Instructions

For Stalk Nitrate sampling, it is important to ensure your sample is collected and sent to the laboratory within a 24-hour period. This analysis can experience a lot of variability if the sample is collected and it sits around for days. To help with this process, Midwest Laboratories is providing Stalk Nitrate bags at no charge that are much easier to use in the field than paper bags.
